A wheel engaging block 3l is placed against the side of the standard 2dremote from the slide 28 and is provided with elongated apertures whichalso receive the bolts 30 and provide for vertical adjustment of theblock 3l relative to the standard 29.

The car block 3! has concavely curved ends, the curvature of which issubstantially the same as the curvature of the tires of the car Wheels42, so that when the car Wheels engage the block, the tires will contacta maximum area of the end surface of the block.

Where the stop is used for stopping vehicles, such as mine cars, theblock 3l may be formed of a hard Wood to reduce the Weight of theportable stop and also reduce the impact shock of the Wheels against theblock and avoid damage to the Wheels.

An apertured lug 32 extends upwardly from' the slide 28 at the end ofthe slide remote from the standard 29 and a rod 33 extendslongitudinally of the bar I and has a screw threaded end portionextending through the aperture in the lug 32. The rod is secured to thelug for rotation relative to the lug but against longitudinal movementrelative thereto by suitable means, such as the nuts Sli threaded ontothe screw threaded portion of the rod and disposed at respectively vperpendicularly extending lever 31 for manuale ly rotating and slidingthe rod relative to the bar i5. This lever 37 is covered by a grip 38 ofelectrically insulative material to protect a person using the car stopagainst accidental electric shocks from the rail l0.

Two stops 39 and fill in the form of short lengths of round iron stockare secured to the flange il at spaced apart locations between the guide3S remote from the rail connected end of the bar and the end of the barl5 remote from the rail connected end thereof. These stops extendtransversely of the flange Il and are secured thereto by suitable means,such as welding.

When the lever 3'.' is permitted to drop, it will engage behind one orthe other of the stops 39 or M3, depending upon the position of the rod,to hold the rod in position against accidental displacement.

Aiter the bar i5 has been connected to the rail It in the mannerindicated above, in order to set the car stop to its operative positionthe lever or handleSi oi the rod 33 is manually raised and theV rod isthen manually slid along the bar towardthe rail i6 until the block 3lrests upon the ralhead Il, as is particularly illustrated in Figures 1and 2. The handle is then released and falls down behind the stop 39 sothat the block cannot be accidentally displaced from the rail.

When it is desired to release the car stop to its inoperative positionso that cars can pass by it,

The rod 33 extends slidably and rotatably the rod handle 31 is raiseduntil it is released from the stop 38 and the rod is then manually slidalong the bar i5 in a direction away from the rail ID until the block 3lis disposed at a location spaced from the outer side of the rail. Thehandle is then released and will fall behind the stop 40 to preventaccidental movement of the block 3l back toward the rail I0. When it isdesired to move the car stop to a diiierent location, it can be releasedfrom the rail i8 by turning the button 25 to its released position andthen drawing the plate i9 and associated elements out from under therail.

The invention may be embodied in other speciic forms without departingfrom the spirit or essential characteristics thereof. The presentembodiment is, therefore, to be considered in all respects asillustrative and not restrictive,.the scope oi the invention beingindicated by the appended claims rather than by the foregoingdescription, and all changes which come within the meaning and range ofequivalency of the claim are, therefore, intended to be embracedtherein.

What is claimed is:

A portable car stop comprising an elongated li .r having a iiange alongat least one edge theremeans secured to said bar near one end there-`for releasably connecting said bar to a track il to extendsubstantially perpendicularly l s efrom, a slide mounted on said bar andensaid frange to restrain said slide against epa-ration from said barwhile permitting slide movement of said slide longitudinally of said aWheel engaging block carried by said slide movable therewith between anoperative pos -ion in which it rests on a rail to which said isconnected and an inoperative position in which it is spaced from oneside of such rail, guides mounted on said bar at spaced apart locationstherealong, a rod extending slidably through said guides and connectedat one end to said slide for manually moving said slide along said Tearbetween the operative and inoperative positions of said block, and stopssecured to said bar at spaced apart locations therealong and engagingsaid rod to releasably lock said slide in the operative or theinoperative position or" said block, said means secured to said bar forreleasably connecting said bar to a track rail comprising a first platesecured to said bar and projecting from one end thereof, a second plateextending across said first plate at said one end of said barsubstantially perpendicular to said rst plate, said second plateextending substantially symmetrically to opposite sides of said rstplate and having its ends disposed at an angle and tapered to provideteeth for engaging rail supporting material, and a button rotativelysecured to said iirst plate adjacent the side of said second plateremote from said bar` SAMUEL L.
